I somehow suspect Anae is playing chess while 99.9% of us on this board are playing checkers. Probably why he's a professional, an offensive coordinator that consistently puts together top 25 offenses, a guy who has learned under Edwards and Leach and Rich Rod...and we are on this board.
After one play, we identified if...and who Hill's spy would be. Sometimes in chess you sacrifice pawns...
Not every play is going to go for 80. Sometimes you run plays to learn tendencies. Sometimes the plays are body shots designed to wear a defense down. And sometimes a play is designed to identify a spy...and the guy you are using is actually capable of busting it for 80. You run the draw, if it doesn't pick up much, so be it. You have identified how they are going to handle Taysom in the running game. If it busts...gravy.
